TECHNICAL FIELD

The present invention relates to the technical field of thermos, inparticular to a thermos having multiple hermetical heat preservationstructures and a glass liner easy to disassemble and assemble.

BACKGROUND

Thermos on the current market mainly comprise bottle bodies and bottlecaps. By threaded connection between the bottle body and the bottle cap,a hermetical heat preservation space is formed. Existing thermos areirregular in quality, and usually cannot achieve a heat preservationeffect. Heat in the bottle bodies is lost too fast, and problems such aspoor airtightness, etc., exist. Secondly, in order to enhance the heatpreservation property of traditional thermos, inner and outer walls ofthe bottle bodies are connected by welding. While in actual use, oncethe inner walls are damaged, the thermos lose the heat preservationproperty, and the thermos cannot continue to be used by replacing theinner walls. For this purpose, there is a need of a thermos which isbetter in airtightness, better in heat preservation property and morereliable and has a replaceable or removable glass liner.

SUMMARY

Objects of the present invention are to overcome defects of the priorart and to provide a thermos having multiple hermetical heatpreservation structures and a glass liner easy to disassemble andassemble.

In order to realize the above objects, the present invention provides athermos having multiple hermetical heat preservation structures and aglass liner easy to disassemble and assemble. The thermos comprises abottle cap, a fixing cap, a water seal piece, a seal ring, the glassliner and a bottle body. External bottle body opening threads andinternal bottle body opening threads are respectively molded on theouter side surface and the inner side surface of a bottle opening of thebottle body, wherein the external bottle body opening threads and theinternal bottle body opening threads are respectively in thread fit withbottle cap threads molded on an inner side surface of the bottle cap andglass liner threads molded on an outer side surface of the glass liner.The seal ring sleeves the outer side surface of the glass liner, whereinwhen the bottle body and the glass liner are connected in a matchingmanner, a lower surface of the seal ring makes contact with a bottleopening edge of the bottle body. The fixing cap and an inner top of thebottle cap are connected in a matching manner. The water seal piecesleeves the fixing cap, wherein when the bottle body and the bottle capare connected in a matching manner, the water seal piece and a bottleopening of the glass liner are matched hermetically.

Further, a fixing boss is formed on the inner top of the bottle cap, andthe fixing boss is connected with a fixing clamping groove formed in thefixing cap in a matching manner.

Further, a plurality of raised ribs is molded on an outer side surfaceof the water seal piece.

Further, an inverted buckle matched with the top end of the fixing capis molded on an inner side surface of the water seal piece.

Further, a vacuum hollow interlayer is disposed in the bottle body.

The present invention adopts the above solution and has the followingbeneficial effects. A thermos hermetical structure is formed by thebottle cap, the fixing cap, the water seal piece, the seal ring, theglass liner and the bottle body. The glass liner and the bottle body areconnected and fixed by the threads. By compressing the seal ringvertically, easiness in replacement of the glass liner and a hermeticaleffect between the glass liner and the bottle body are realized. Thebottle opening of the glass liner and the water seal piece cooperatewith each other, thereby achieving water leakage preventing andhermetical effects. Meanwhile, by matching and connection among thebottle cap, the fixing cap and the water seal piece as well as thevacuum hollow interlayer of the bottle body, heat exchange between heatin the glass liner and external air is isolated. A heat preservationproperty of the thermos is further improved. Secondly, the glass linerhas the characteristics of easiness in replacement and removal.Therefore, the thermos is enabled to be more durable, and the bottlebody can be directly used by removing the glass liner.

DETAILED DESCRIPTION

The present invention is further explained in combination with specificembodiments.

Referring to FIGS. 1 to 11, in the present embodiment, a thermos havingmultiple hermetical heat preservation structures and a glass liner easyto disassemble and assemble comprises a bottle cap 2, a fixing cap 5, awater seal piece 6, a seal ring 4, a glass liner 3 and a bottle body 1.External bottle body opening threads 11 and internal bottle body openingthreads 12 are respectively molded on the outer side surface and theinner side surface of a bottle opening of the bottle body 1, wherein theexternal bottle body opening threads 11 and the internal bottle bodyopening threads 12 are respectively in thread fit with bottle capthreads 22 molded on an inner side surface of the bottle cap 2 and glassliner threads 31 molded on an outer side surface of the glass liner 3.The seal ring 4 sleeves the outer side surface of the glass liner 3,wherein when the bottle body 1 and the glass liner 3 are in threadedconnection, a lower edge surface of the seal ring 4 makes contact withan opening edge of the bottle body 1, and a hermetical effect isachieved by compressing the seal ring 4 vertically through the bottlebody 1 and the glass liner 3. A fixing boss 21 is formed on the innertop of the bottle cap 2. The fixing cap 5 is provided with a fixingclamping groove 51 matched with the fixing boss 21. The water seal piece6 sleeves the fixing cap 5, wherein an inverted buckle 62 matched withthe top end of the fixing cap 5 is molded on an inner side surface ofthe water seal piece 6. By disposing the inverted buckle 62, the waterseal piece 6 can be more firmly connected to the fixing cap 5. Acondition that the airtightness becomes poor caused by falling of thewater seal piece 6 is avoided. A plurality of raised ribs 61 is moldedon an outer side surface of the water seal piece 6. After the bottlebody 1 and the bottle cap 2 are connected in a matching manner, thewater seal piece 6 and the inner side surface of the glass liner 3 arematched. The water seal piece 6 prevents water leakage and achieves ahermetical effect with the glass liner 3. The plurality of raised ribs61 is disposed to make contact with the inner side surface of the bottleopening of the glass liner 3. Therefore, the airtightness between thewater seal piece 6 and the glass liner 3 is further enhanced. A hollowinterlayer is disposed in the bottle body 1. When the glass liner 3 isplaced in the bottle body 1, the heat of liquid in the glass liner 3conduced out of the bottle body 1 via the bottle body 1 to be subjectedto heat exchange with air is reduced. Therefore, heat loss is reduced.By formation and cooperative use of the above components, the thermoshas multiple hermetical heat preservation structures. Therefore, theheat preservation property, reliability and airtightness of the thermosare further improved. Secondly, due to the characteristic of easiness indisassembly and assembly of the glass liner 3, the thermos has thecharacteristic of a replaceable or removable glass liner 3. Further, thethermos is enabled to be more durable. Meanwhile, when the glass liner 3is damaged but not replaced yet or the glass liner 3 is not usedaccording to the needs, the bottle body 1 can be directly used byremoving the glass liner 3.
